Apple to refresh iMac lineup with M6 chip this year

Apple is reportedly preparing to refresh its iMac lineup with the M6 chip before the end of 2026, according to Bloomberg's Mark Gurman. The new model is expected to keep the current M4 design with only minor color tweaks, and the M6 generation may have a short lifecycle before an M7 transition in early 2027.

M6 iMac refresh on the horizon

Apple is reportedly gearing up to refresh its iMac lineup with the new M6 chip, with the update expected before the end of 2026. The information comes from Bloomberg's Mark Gurman, as reported by NewsBytes. According to that report, the new model will likely retain the look and feel of the current M4-generation iMac, with possible tweaks in color options. Those expecting a major redesign or new features from this upgrade are likely to be disappointed, as the report explicitly cautions against expecting any major changes.

Short product lifecycle and chip strategy

The M6 generation is expected to have a notably short product lifecycle, possibly lasting just six months, according to the NewsBytes report. This would be a departure from the year-or-more cycle seen with previous Apple Silicon releases. The report also speculates that Apple will only use the base model of the M6 chip, skipping over the Pro, Max, and Ultra variants entirely, and that the company is expected to transition to the next-generation M7 chip in the first half of 2027.

Technical expectations for the M6 chip

In terms of specifications, the M6 chip is expected to deliver a significant boost in memory bandwidth, reaching 200GB/s, along with a new memory architecture and a 12-core GPU, according to NewsBytes. This would represent a major upgrade over the current generation of iMacs, which use the M4 chip with lower memory bandwidth and fewer GPU cores.

Context: New Mac Studio models announced

On a related note, Apple today unveiled new Mac Studio models with M5 Max and M5 Ultra chips, as reported by MacRumors. Pre-orders for these new machines began today ahead of a September 22 launch, but one configuration will not be available until later. Apple says the Mac Studio with the M5 Ultra chip and 512GB of RAM will be arriving in "late October," with U.S. pricing expected to start well above the $10,000 mark.

The delay for that specific configuration is noteworthy because Apple stopped offering the previous-generation Mac Studio with 512GB of RAM in March due to the ongoing memory chip shortage. The upgrading option is expected to return for the new model in about two months from now, though the launch date for this top-tier configuration is later than the general launch.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
